  • Why is PAC used as a Lewis acid catalyst?
  • In this work, PAC has been used as a Lewis acid catalyst in interdisciplinary fields because of its polynuclear Al–O cation structure. Further, its catalytic mechanism in green organic synthesis has been studied in detail by using the multicomponent Biginelli reaction as the probe.
  • Is PAC a good catalyst for organic synthesis?
  • The PAC–ethanol system is, therefore, considered to be a green, efficient (best yield >99%), economic and recyclable catalyst for catalyzing organic synthesis reactions. The development and utilization of PAC materials in organic synthesis will bring new vitality to this cheap material, which is widely used in industries.
  • Do PAC materials have different morphological characteristics in different solvents?
  • The results show that the PAC materials have different morphological characteristics in different solvents. The Al–O–Al cations were transformed in the ethanol solvent to form new multi-nuclear cation aggregates Al b, which could be used as inorganic micro–nano reactors with unique synergistic catalysis in catalytic reactions.
